We will integrate iphone's chschess with facebook later, yet not now. All levels are stored locally. You can play this game to verify your chess level!

This is the chess to test your levels, so you cannot do the followings:1) undo moves2) restart new game when it is not the end;3) you can't choose the level because the system will let you stop at your right level.

Probably what we should add is a Lose button, to surrender to computer if you will absolutely lose.

And we are thinking to add a practice mode, so you can :1) undo moves2) select levels3) restart game at any time.
